get a sub rated around half that. 600watts. basic entry level subs in a custom box should be good.

is it 1 ohm or 2 ohm stable?you wanna run 10s 12s 15s what size and how many? also what are you trying to get from your system .sound quality.lots of bass or just some bass to fill in the lack of

that amplifier does 600 watts bridged at 4 ohms

find a woofer that is 600 watts RMS and has either:

A. a single 4 ohm voice coil

B. dual 2 ohm voice coils (to run in series)

C. dual 8 ohm voice coils (to run in parallel)

that site is an educational resource for car audio - it has a menu going down the right side, click on the various words and concepts and it explains them much better than I can.

I would probably, to keep you install easy go with a subwoofer that has single voice coil 4 ohms, that way you can just go pos to pos and neg to neg on the wiring. To answer your question ohm is a measure of resistance and has alot to do with the power output of the amplifier. I would recommend something like a JL w3, it is a good starter subwoofer and pretty clean so it will complement that bose system. As far as hooking it up to you factory HU, this may be a little tricky for someone who doesn't know much about installing. But, what you need is a line out converter and you need to find the base amp, wherever it is in that car try Car Alarm, Car Stereo, Mobile Video, and Cruise Control Info for Installers for help, and you want to tie the LOC into the front right and left speaker outputs from that amp. The LOC will give you RCA out which you run to the amp. Good luck bud

so, what i've got so far from all this is i need a sub with 600rms and that it would help if it has a single voice coil 4 ohms. does anybody know of any sub (not to expensive, below $100 would be great) that matches this descripton, and like CivicGti said before, would go well with my stock Bose system???

the sub must be 8 or 10" like stated before

That amp only has 2 40a fuses and is about 60% efficient. I imagine getting no more than 350 true watts out of it. I wouldnt put anything more than a sony xplod on it.

 

[youbeenblown 10+ year member]

do you suggest another amp? (i currently dont own the amp i was going to make a trade for it but i can call it off). im on a budget though so like said above id like to keep prices down

 

[All_Logix 10+ year member]

Don't worry to much about another amp right now, I mean you already have it, try it out, then grow into needing another amp. If you want to stay close to 100 you could give these a look Polk Audio MM1040DVC (MM-1040DVC) 10" Mobile Monitor Car Subwoofer

guys ur help really means alot honestly. thanks so much. any other advice you'd happen to have? also the dudes asking 70$ for the amp (again its a 1200watt poweracoustic saphire) do you think its a fair price or should i get something else?

 

[I Like Waffle]

how much money do you have for an amp and sub? You going for loud or SQ? I will make a recommendation to max your budget, and if you dont listen you can **** off.

 

[youbeenblown 10+ year member]

waffle's very grumpy anyways like i said my budget is around 100$ each (100 for sub 100 for amp). i'd like something thatll be able to hit the high and low pretty good. a like alot of bass. not to crazy though.
